Why does technology change over time, how does it change, and what difference does it make? In this sweeping, ambitious look at a thousand years of Western experience, Robert Friedel argues that technological change comes largely through the pursuit of improvement—the deep-rooted belief that things could be done in a better way. What Friedel calls the "culture of improvement" is manifested every day in the ways people carry out their tasks in life—from tilling fields and raising children to waging war.
